2023年7月17日 · Total anomalous pulmonary venous connections (TAPVC) is a cyanotic congenital heart disease where all of the pulmonary veins drain directly or indirectly into the right atrium.

In TAPVC, the blood does not take the normal route from the lungs to the heart and out to the body. Instead, the veins from the lungs attach to the heart in abnormal positions and this problem means that oxygenated blood enters or leaks into the wrong chamber. What causes it? In most children, the cause isn't known.

anomalous pulmonary venous connection (TAPVC) is a rare but heterogeneous anomaly, accounting for ≈1% to 3% of congenital heart disease cases.1 It is characterized by failure of the pulmonary venous conflu-ence (PVC) to be absorbed into the dorsal portion of the left atrium (LA) in combination with a persistent splanchnic connection to the ...

2023年6月20日 · Transesophageal echocardiography (TEE) provides improved PV visualization and functional assessment of stenosis severity/flow velocity. 23 PVS presents as narrowed PV ostial diameter, elevated diastolic peak velocity (>0.9-1.1 m/s) on pulsed-wave Doppler, or turbulent flow. 23 TEE advantages include the lack of ionizing radiation and ...

Total anomalous pulmonary venous connection (TAPVC), also referred to as total anomalous pulmonary venous return (TAPVR), is a cyanotic congenital defect in which all four pulmonary veins fail to make their normal connection to the left atrium. This results in drainage of all pulmonary venous return into the systemic venous circulation.

Transthoracic echocardiography (TTE) can accurately diagnose TAPVC, and the precise pattern of venous drainage can be delineated. 4, 5 Intraoperative transesophageal echocardiography (TEE) complements TTE and can be used to confirm …

2021年1月5日 · Transesophageal echocardiography (TEE) is also helpful. Evaluate drainage and connection of pulmonary veins by TEE in 55° for right, and 110° for left pulmonary veins. When imaging venous flow with color flow Doppler, reduce the Nyquist limit to correspond to the lower venous flow velocities (Fig. 11.3). 3.

2025年1月31日 · Total anomalous pulmonary venous return (TAPVR) is a cyanotic congenital heart anomaly with abnormal drainage anatomy of the entire pulmonary venous system. This contrasts with partial anomalous pulmonary venous return (PAPVR) where only part of the pulmonary venous anatomy is abnormal.

Total Anomalous Pulmonary Venous Return Guideline What the Nurse Caring for a Patient with CHD Needs to Know

2007年3月12日 · TOTAL ANOMALOUS PULMONARY VENOUS CONNECTION (TAPVC) is a congenital heart defect in which there is no connection between the pulmonary veins and the left atrium. AN ANOMALOUS CONNECTION is established that allows the pulmonary veins to deliver pulmonary venous blood to the right side of the heart rather than to the left side.
